The luxury liner SS United States completed its journey Monday from South Philadelphia to Alabama, where it will undergo preparations before it is sunk in the waters off Florida's Gulf Coast to become an artificial reef.

The SS United States, the former luxury ocean liner that was parked in South Philadelphia for almost 30 years, has reached Mobile, Ala., faster than expected and in one piece, proving skeptics wrong.

The SS United States began its final approach into Mobile, Alabama, Monday morning, marking the end of the first leg of its journey to becoming the world's largest artificial reef.
